Bicycle

transportation · human-powered · two-wheeled · exercise

Powered by your legs. A bicycle works because you push the pedals with your feet, and that spinning motion transfers through a chain to make the wheels turn. No engine needed, just your own muscle power.

Connected by a chain. When you pedal, you're turning a gear called a chainring, and a metal chain carries that spinning motion to another gear on the back wheel. This clever system lets you move forward efficiently.

Balance and steering. Riding a bike means balancing on two wheels while steering with handlebars connected to the front wheel. Your body naturally leans and shifts to keep you upright as you move.

Single track vehicle. A bicycle follows a single path because both wheels line up one behind the other, making it narrow and nimble compared to cars or trucks. This is why bikes can squeeze through tight spaces and navigate busy streets.

Friendly to the planet. Bicycles produce zero pollution and use only your energy to move, making them one of the greenest ways to travel anywhere.
